[0002] In the industrial production process of flour food, dough flattening as a key link between the former and the latter directly affects the quality stability of the subsequent forming, steaming and cooking processes. In the process of flattening dough into dough sheets, the mechanical calendering method is generally used. Specifically, two groups of horizontally arranged smooth metal rollers are used as the main working unit. The thickness of the dough is controlled by adjusting the roller spacing. The process needs to be matched with a tensioning conveyor belt system to ensure continuous feeding of the material. A scraping device is provided at the outlet end to prevent residual adhesion. In actual production, the equipment operating parameters need to be dynamically adjusted according to factors such as flour tenacity, moisture content and additive ratio. The common processing speed range is a certain interval value. For special formulations containing particulate fillers or high-fiber ingredients, they are usually pre-treated by mixing and homogenization before entering the flattening stage.

A cover is installed on the support table, a hydraulic cylinder is installed on the cover, a bracket is installed on the moving end of the hydraulic cylinder, an inclined conveyor belt is arranged on the bracket, and an adjusting roller is installed above the mirror roller on the bracket.

[0004] In use, the dough is placed on the transmission belt, and the transmission belt drives the dough to move. When the dough passes through the conveyor belt, the transmission conveyor belt also applies a forward thrust to the dough, and the dough is flattened by the extrusion of the mirror roller and the adjusting roller under the guidance of the transmission belt and the conveyor belt.
